I'm trying to understand the cycle of rebirth mentioned in the text. What does Chapter 37 say causes a person to be stuck in the cycle of birth and death?

According to Chapter 37, the primary cause for being trapped in the eternal cycle of worldly existence, or Samsara, is the mistaken knowledge of difference. When a person believes, "Parabrahman is different from me; I am not that," they create a sense of separation from the ultimate reality. This delusion, born of ignorance, subjects the individual to the continuous loop where death follows birth and rebirth follows death. The text from Chapter 37 emphasizes that this cycle turns eternally behind one who holds such a dualistic view, contrasting with the unified vision of seeing the same divine principle in all things.
